如何在批量电子邮件循环中包含PHPMailer？

require 'vendor/autoload.php';  // 引入PHPMailer库

// 创建收件人列表
$recipients = array(
    'recipient1@example.com',
    'recipient2@example.com',
    'recipient3@example.com'
);

// 实例化PHPMailer对象
$mail = new PHPMailer\PHPMailer\PHPMailer();

// 配置SMTP服务器和认证方式
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->Port = 587;
$mail->SMTPAuth = true;
$mail->Username = 'your-email@example.com';
$mail->Password = 'your-password';

// 设置发件人信息
$mail->setFrom('your-email@example.com', 'Your Name');

// 循环发送邮件
foreach ($recipients as $recipient) {
    $mail->addAddress($recipient);  // 添加收件人地址
    $mail->Subject = 'Your Subject';  // 设置主题
    $mail->Body = 'Your email body';  // 设置正文内容

    // 添加附件（可选）
    // $mail->addAttachment('/path/to/file.pdf');

    // 发送邮件并检查返回值
    if ($mail->send()) {
        echo "Email sent to: $recipient<br>";
    } else {
        echo "Failed to send email to: $recipient. Error: {$mail->ErrorInfo}<br>";
    }

    $mail->clearAddresses();  // 清除收件人列表
}
